ANTIJEREEZING DEVICE FOR RADIATORS.

Application filed November 24, 1920. Serial No. 426,205.

To all whom it may concern:

Be it known that I, THEODORE A. MILU- rm, citizen of the United States,residing; at Deal-born, county of \Vayne, State of Michigan, haveinvented a certain new and useful Improvement in Antitreezing Devicesfor Radiators, and declare the following to be a full, clear, and exactdescription of the same, such as will enable others skilled in the artto which it pertains to make and use the same. reference being had tothe accompanying drawings, which form a part of this specification.

My invention relates to a device designed to insure the watercirculating through the cooling system. of an internal combustion engineagainst freezing during cold weather when the engine is not inoperation.

The object of the invention is to provide means whereby the water may bedrained from the cooling system and delivered to an anti-freezingcontainer designed to maintain the water at a sufficiently hightemperature that it may not freeze and to return the warm water to thecirculating system of the engine that its heat may aid the ignition ofthe gas delivered to the combustion chamber of the latter.

ln putting this invention into effect a pump is employed adapted todrain the water from the water cooling circulating system of the engineupon parking the m.otor vehicle for any considerable period or uponhousing the car over night, the water being delivered thereby into aheat retaining container of the so called thermos type, from which thewarm water is afterwards withdrawn and returned to the water circulatingsystem of the engine when it is again desired to drive the vehicle ;thepump being operated either manually or through power derived from theusual starter employed to crank the engine.

A further object of the invention is to provide means whereby theoperation of the pump and the delivery of water to and from the watercirculating system. may be controlled from the drivers seat.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention further resides in the combinationand arrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes may be made inthe precise embodiment of the invention herein disclosed withoutdeparting from the spirit'of the same.

pipes leading therefrom to a plural valve casing, 1n turn connected withthe radiator of an internal combustion engine,' as installed upon motorvehicles,the valves housed in the casing being adapted to control thepassage of water to and from the radiator and to and from a heatretaining water container,-the view shows the position occupied by thevalves when the water is passlng from the heat retaining water containerback to the radiator.

Referring now to the heat-retaining water chamber W shown in Figures 1and 2 of the drawings, W W W designate a. plural number of water tanksinadjacent relation to each other and preferably located beneath thedrivers seat. The tanks each consist of an inner chamber W spaced fromthe outer chamber, the construction being somewhat similarin principleto the so-called thermos. bottle.

t, denotes a three-way valve located in the chamber P directly below thepipe Q,

adapted to admit the delivery of water to the pipe Q when in theposition shown in Figure 2, or the-withdrawal of the water from theradiator when in the position shown in Figure 3.

S and Trespectively denote two two-way valves housed in the valvechamber P;--

S is a passage connecting the chamber 1 S in the valve chamber P with apassage T, in turn communicating with a pipe T leading to theheat-retaining water chamber W;preferably located beneath the driversseat (see Figure 1). g

The passage S in the plural valvev chamher is under the control of acheck-valve S is a screw plug through which access may be had to thecheck-valve. In order to providefor the synchronous operation of thevalves R, S, and T, they are respectively fitted with segmentalintermleshing gears R, S, and T.

W s a gear mounted on an end of the pipe W, 111' mesh with anidle-gear W which in turn meshes with a segmental gear W on the end ofan operating lever W mounted on the rod W -which is also journaled inthe upward extension of the tank walls. W, W, W are closure capssupported on arms W apted upon the o eration of the lever W tosimultaneously close the necksW of the several tanks.
